Everyone has a different play style. See below for mine.
==Autoplay per hour==
==Mobile Gaming==
I use my smartphone for many things, reading the forum, playing games besides Empires, messaging friends, talking to friends, etc.
While my smartphone is busy farming recruits, I cannot use it for anything else.
Faster recruit farming frees my smartphone for other uses.
==Boredom==
I have to check my smartphone periodically to see if it is ready to autoplay the next stage or replay a stage.
Faster recruit farming frees up my real world time for other uses.
==Memory and Batteries==
Unfortunately my smartphone uses a limited type of memory ( flash memory ) and a high performance, moderate durability battery ( lithium ion film ). While both are rated for two years, heavy use can degrade both the performance, and the maximum capacity, of both. The battery is especially susceptible to degradation due to heat caused by high graphic processes.
Faster recruit farming puts less wear on physical components extending the performance and life of my smartphone.
==Stages of Recruits II Quest==
Breaking down Recruits II per stage versus s1-7-7
Easy 20 recruits- same as fighting 4.6 mob waves and 2.3 bosses
Medium 25 recruits- same as fighting 5.8 mob waves and 2.9 bosses
Challenging 35 recruits- same as fighting 8.1 mob waves and 4.0 bosses
Breaking down Recruits II per stage versus s1-8-7.
Easy 20 recruits- same as fighting 6.8 mob waves and 4.5 bosses
Medium 25 recruits- same as fighting 8.5 mob waves and 5.6 bosses
Challenging 35 recruits- same as fighting 11.9 mob waves and 7.9 bosses
Even breaking down the stages separately, speed farming Recruits II is faster since you fight significantly less mob waves and bosses than running s1-7-7 or s1-8-7.
==Free World Energy==
Free, or bought, leveling a rainbow team of 5* 4.80 takes 10,910 recruits or about 674 hours of free WE. Luckily I can regenerate free World energy while my smartphone is off.
However, to spend world energy my smartphone must be farming.
To farm 10,910 recruits, using only “Recruits I” takes my smartphone 13.225 hours, using only “Recruits II” takes my smartphone 20.3 hours, using only s1-7-7 takes my smartphone 24.63 hours, using only s1-8-7 takes my smartphone 32.2 hours.
While “Recruits II” is not as fast as “Recruits I” is is still faster than s1-7-7 and significantly faster than s1-8-7. So every stage of “Recruits I” and “Recruits II” is time I have for other stuff.
Like writing very, very, very long posts to the forum.
